Gapps and google play stopped workingSupport

Hi .. I recently upgraded my phone xperia mini pro SK17i 's software from GB to ICS 4.0.4 and rooted my phone.
After rooting i installed Titanium backup and remove a few what i thought were unnecessary apps from my phone .
I think i also deleted the google.download.manager.apk i'm not sure but i cannot see this service in my "ALL APPS" (APP Manager) Its not at the bottom or disabled its just not there.

Since then i keep getting gapps stopped working and Google play stopped working .
i have tried
1. Rebooting (multiple times)
2. Clearing cache/clearing data for Play
3. un-installing /Re Install play
4. Download goomanager and downloading latest gapps packed and flashed the zip
5. Delete gmail account and restart and add account again.

Also i don't think there is prob in Google sync...

and checked out all the sites and forums for solution ... i still haven't gotten any solution to this.
i saw in a few places about QtADB and new ROM..but i have abs no clue about what it is or how to go about it

I jst want the Google download manager back and Google Play to work...
